Sidla ngokuthetha ngoshicilelo, ngokusebenzisa indlela ethile yokudlulisa i-inki kwindawo ethile yephepha, ukuze sifune ukufumana amagama okanye imizobo.
Imichiza eyenza iphepha ayikufunxanga kangako ukukhanya kwawo nawuphi na umbala, ngoko xa ukukhanya kuvela kumphezulu wephepha namehlo ethu, sikubona kumhlophe.
I-pigment okanye idayi ekwi-inki ifunxa okunye okanye konke ukukhanya okubonakalayo, ukuze xa i-inki ifakwe kumphezulu wephepha, umphezulu wephepha elimhlophe uba nemibala.
Iintlobo eziphambili zabashicileli esizisebenzisayo ekhaya okanye eofisini ngabashicileli be-inkjet kunye nabashicileli belaser.
Ngokungafaniyo nabashicileli be-inkjet, abatshiza amathontsi amancinane e-inki ephepheni, abashicileli belaser batsalela iitoner kwigubu elikhanyayo baze bazidlulisele ephepheni ngokutsala umtsalane wombane.
Nangona kunjalo, irisithi ayiprintwa ngolu hlobo. Iprintwa kuhlobo oluthile lwephepha, olubizwa ngokuba yi-thermal paper.
Xa kuthelekiswa nephepha eliqhelekileyo, iphepha le-thermosensitive linombala obhityileyo kumphezulu walo, onemichiza ekhethekileyo ebizwa ngokuba ziidayi ezifihlakeleyo.
Idayi eyimfama ngokwayo ayinambala, ngoko ke iphepha elisanda kuthengwa le-thermal libukeka limhlophe njengephepha eliqhelekileyo.
Noko ke, xa iimeko ezifanelekileyo zihlangatyezwana nazo, zisabela ngokwemichiza, yaye izinto ezintsha zifunxa ukukhanya okubonakalayo, yaye sibona umbala.
Izinto ezininzi, ezifana necrystalline violet lactone, nangona ngokwemvelo zingenambala, zijika zibe mfusa xa kukho iasidi.
Oko kukuthi, xa siprinta kwiphepha le-thermosensitive, i-inki ayigcinwanga kwiprinta, sele isele kwiphepha.

Umfanekiso
Umzobo 1 Icrystalline violet lactone iya kutshintsha ukusuka ekungabinambala ukuya kwimfusa xa kukho izinto ezineasidi, kwaye iya kuphinda ingabinambala kwakhona xa kukho izinto zealkaline.

Kodwa i-cryptic dyes efana ne-crystallactone, ephendula ngokulula kunye ne-acids, iqinile kwiqondo lokushisa, kwaye iimolekyuli zivaliwe kwindawo.
Ukuba ujongana ne-asidi ekwaqinile, ninokuhlala kunye ixesha elide kwiqondo lobushushu begumbi, nokuba ninxibelelana ngokusondeleyo.
Ngoko ke, sinokuthatha ezi dayi ezimnyama, eziqinileyo kwiqondo lokushisa, kwaye sigaye into eqinileyo yenye into ene-asidi ibe ngumgubo ocolekileyo, udibanise kwaye uqabe phezu kwephepha, kwaye sifumana iphepha le-thermal.
Kwiqondo lobushushu begumbi, iphepha le-thermal libukeka njengephepha eliqhelekileyo;
Ngokukhawuleza xa izinga lokushisa liphakama, idayi emnyama kunye ne-asidi iyanyibilika ibe yi-liquid, kwaye ii-molecule ezihambayo zamahhala zidibana kwaye ziphendule ngokukhawuleza, ngoko iphepha elimhlophe libonisa ngokukhawuleza umbala.
Apha kulapho iphepha le-thermosensitive lifumana khona igama-- liba shushu ngokwaneleyo ukuba litshintshe umbala.
Ngephepha le-thermal, ukuba ufuna ukuprinta okubhaliweyo okanye imizobo kumphezulu wayo, ufuna kwakhona umshicileli okhethekileyo, ongumshicileli we-thermal.
Ukuba ukhe waphula umshicileli we-thermal, uya kufumanisa ukuba ingaphakathi layo lilula kakhulu: akukho khatriji ye-inki. Amalungu aphambili yigubu kunye nentloko yoshicilelo.
Iphepha le-thermal elisetyenziselwa ukuprinta iirisithi ngokuqhelekileyo lenziwa kwimiqulu.
Xa umqulu wephepha le-thermal ubekwe kumshicileli, uqhutyelwa phambili yi-roller kwaye udibana nentloko yokushicilela.
Kukho izinto ezininzi ezincinci zesemiconductor kumphezulu wentloko yoshicilelo ezifudumeza iindawo ezithile zephepha ngokwamagama okanye imizobo esifuna ukuyiprinta.
Ngomzuzu woqhagamshelwano phakathi kwephepha elishushu kunye nentloko yoshicilelo, ubushushu obuphezulu obuveliswa yintloko yoshicilelo lenza idayi kunye ne-asidi kumphezulu wephepha le-thermal inyibilike ibe lulwelo kwaye isabele ngokwekhemikhali, ngaloo ndlela umphezulu wephepha ubonakala unobumba okanye imizobo. .
Ukuchithwa yi-roller, irisithi yokuthenga iprintwa.
Umfanekiso
Umzobo we-2 Umgaqo wokusebenza womshicileli we-thermal: iphepha le-thermal liqhubela phambili liqhutywa yi-drum. Xa idibana nentloko yoshicilelo, ubushushu obuveliswa yintloko yoshicilelo bunyibilikisa idayi kunye ne-asidi kumphezulu wephepha le-thermal, kwaye ezi zimbini zisabela ngemichiza ukuvelisa umbala.

Kutheni amashishini esebenzisa iphepha le-thermal kunye nabashicileli be-thermal ukuprinta iirisithi zokuthenga, kunokuba abashicileli belaser okanye be-inkjet abaqhelekileyo?
Okokuqala, i-laser okanye iiprinta ze-inkjet zifuna izixhobo eziyinkimbinkimbi ukudlulisa i-inki okanye i-toner ukusuka kumshicileli ukuya kwiphepha. Bobabini abashicileli baninzi kwaye bahlala besebenzisa umsinga otshintshanayo njengonikezelo lwamandla abo.
Amashishini ahlala efuna abashicileli abancinci, ngakumbi xa bethengisa iimpahla ngaphandle okanye kwizixhobo zothutho ezifana neenqwelomoya kunye noololiwe, ukuthwala abashicileli abanzima ukuprinta iirisithi zabathengi ngokucacileyo akwenzeki.
Okwesibini, i-laser okanye i-inkjet umshicileli wokutshintsha iikhatriji ze-inki okanye i-toner ihlala idla ixesha kwaye inzima, ukuba ilibazisa ukuthengwa kwabathengi, okukwanqabile kakhulu ukubona ishishini kunye nabathengi.
Ezi ngxaki zinokusonjululwa ngokusebenzisa abashicileli be-thermal kunye nephepha le-thermal endaweni ye-laser okanye iiprinta ze-inkjet.
Ngenxa yokuba i-inki sele igcinwe ephepheni, abashicileli be-thermal abafuni izakhiwo ezintsonkothileyo zokugcina kunye nokudlulisa i-inki kwaye zincinci kakhulu.
Ikwasebenza ngebhetri, nto leyo eyenza ukuba ilungele ukuba amashishini aziphathe, ngakumbi xa engaphandle okanye ekwisithuthi, ukuprinta iirisithi zabathengi.
Ngenxa yolwakhiwo olulula, umshicileli we-thermal ukwalula ukuyigcina, kwaye abasebenzisi abanaxhala lokutshintsha iikhatriji zeinki. Banokutshintsha ngokulula umqulu omtsha wephepha le-thermal nje ukuba iphepha lisetyenziswe. Oku kuqinisekisa ukuba abathengi abalahlekelwa lixesha elininzi.
Ukongeza, isantya sokushicilela umshicileli we-thermal, ingxolo ephantsi, ifaneleke kakhulu ukusetyenziswa kwindawo yokuthenga.
Ngenxa yezi nzuzo, ukuprintwa kwe-thermal ayisiyiyo kuphela indlela ekhethwayo yokuprinta iirisithi zokuthenga, kodwa isetyenziselwa ukuprinta amatikiti, iilebhile kunye neefeksi.
Iphepha le-Thermosensitive nalo line-drawback enkulu, yokuba ukubhala kuxwebhu oluprintiweyo kuya kuphelelwa lixesha.
Ukuncipha kwakhona kwenzeka ngenxa yeedayi ezizodwa ezisetyenziswa kwiphepha le-thermal.
Njengoko sichazile ngaphambili, idayi ye-cryptic egubungela iphepha le-thermal ayinambala kwiqondo lokushisa, kwaye iba sesinye isakhiwo esinombala ngenxa yokusabela kweekhemikhali kwiqondo lokushisa eliphezulu.
Nangona kunjalo, isakhiwo esitsha asizinzile kangako, kwaye phantsi kweemeko ezifanelekileyo sibuyela kwisakhiwo sangaphambili esingenambala.
Ngokomzekelo, icrystalline violet lactone, njengoko sesichazile ngaphambili, ijika ibe yimibala enemibala xa kukho into eneasidi, yaye esi sakhiwo sinombala sibuyela kwisimo esingenambala xa kukho ialkaline.
Emva kokuba irisithi eprintiweyo igciniwe, inokudibana neentlobo ngeentlobo zeekhemikhali okusingqongileyo. Isenokutshiswa lilanga okanye amaqondo obushushu aphezulu, nto leyo enokubangela ukuba idayi ekwiphepha le-thermal ibuyele kwimeko yayo engenambala, nto leyo ebangela ukuba irisiti ibe mnyama.
Ukucombulula le ngxaki, abaninzi abenzi bamaphepha ashushu bongeza ukhuselo olongezelelekileyo phezu kwedayi ukuze banciphise ukudityaniswa kwedayi neminye imichiza baze benze amaxwebhu ashicilelwe kwiphepha le-thermal ahlale ixesha elide.
Kodwa le ndlela iya kwandisa iindleko zephepha le-thermal, ngoko kuya kubakho amashishini ukuba aqhubeke esebenzisa akukho lukhuselo lwephepha eliqhelekileyo le-thermal.
Ukuba unexhala lokuba irisithi yakho iya kuphelelwa ngokuhamba kwexesha, isoloko ingumbono olungileyo ukukopa okanye ukuskena irisithi yakho.
Kwiminyaka yakutshanje, iphepha le-thermosensitive libangele inkxalabo phakathi kwabathengi abaninzi kuba liqulethe i-bisphenol A.
I-Bisphenol A yinto eneasidi, ngoko ke isetyenziswa kwiphepha le-thermosensitive apho idibana nedayi ezimnyama kumaqondo obushushu aphezulu ukuvelisa umbala.
Ukongeza, i-bisphenol A isetyenziswa ngokuqhelekileyo njengeMathiriyeli ekrwada ukwenza iiplastiki okanye iingubo ezithile.
Ngoko eyona ndlela iphambili iBPA ingena ngayo emzimbeni kuxa ufaka ukutya kwezi zikhongozeli, intwana ye-BPA ingena emzimbeni kunye nokutya.
Kodwa kwiminyaka yakutshanje, uphononongo lubonise ukuba ukuvezwa kwamanqaku ashicilelwe kwiphepha elingeva bubushushu kunokubangela ukuba i-BPA ingene emzimbeni.
Olunye uphononongo lwakutsha nje, umzekelo, lufumanise ukuba amanqanaba e-BPA kumchamo anda emva kokuvezwa ixesha elide kwiphepha elingeva bubushushu.
Ngenxa yokuba i-bisphenol A's chemical structure ifana ne-estradiol, eyona nto iphambili ye-estrogen eyenziwa ngumzimba, kukho inkxalabo yokuba inokuphazamisa ukukhuselwa kwe-endocrine eqhelekileyo kunye nokwandisa ingozi yezifo ezininzi.
Nangona kunjalo, kubalulekile ukubonisa ukuba ukugxilwa kwe-BPA emzimbeni ngokutya kunye nephepha le-thermal liphantsi kakhulu, ngoko kunzima ukuqinisekisa imiphumo yezempilo ye-BPA kubantu.
Nangona kunjalo, ngelixa i-BPA ingavinjelwanga ngoku kwimveliso yephepha le-thermal, abaninzi abavelisi baye baqala ukusebenzisa ezinye ii-acids endaweni yoko.
Ukuba unenkxalabo malunga Ixabiso elincinci le-BPA elingena kwisistim sakho ukusuka ekudibaneni neerisithi, Inyathelo lokulumkisa ngakumbi kukugcina iirisithi zibekwe zodwa ngokukhawuleza kangangoko ngaphandle kokuzichukumisa, kwaye uhlambe izandla zakho emva kokubamba iirisithi.
Kambe ke, ukutshintsha iirisithi zamaphepha endaweni yezombane kusenokuba sempilweni ngakumbi kwaye kunobungani nokusingqongileyo.
